3.4. Operating Expenses and Operating Income
Lesson objective
Evaluate operations before financing and taxes.
Operating Expenses include items such as research, sales, administration, and other operating costs. Operating Income remains after subtracting those expenses from Gross Profit.
A company may reduce expenses and increase short-term profit while weakening future innovation or sales. Another may invest aggressively today to build future capacity.
Operating Margin helps evaluate scalability, but it should be read together with growth and strategy.
From gross profit to operating profit
Operating income = Gross profit − Operating expenses
Operating margin = Operating income ÷ Revenue
Operating leverage
Revenue grows from $100 to $120 (+20%). Gross profit grows from $60 to $72, while operating expenses rise from $40 to only $44. Operating income rises from $20 to $28 (+40%). Profit grew faster because part of the cost base did not rise as quickly as sales.
Good spending vs. bad spending
Higher operating expense is not automatically negative. R&D or sales investment may reduce current margin while building future growth. Ask whether the spending is producing durable economic returns.
In Finzati
Review Operating Margin in Company Snapshot and its trend in the financial statements.
What you should remember
- Distinguish sustainable efficiency from harmful cost cutting.
- Use multi-year trends.
Practice
Compare the growth of Revenue with the growth of Operating Expenses.
